Some animals like to come out at night.
They are called nocturnal animals.
 |
Bats like to come out at night. They have a special way to hear sounds which help them to find their way at night. They don't have special eyes to see at night. |
 |
The bobcat can see during the day and at night. He has eyes which are made to do this. |
|
The bobcat's eye is like the yellow one. His pupil can change shape from very thin to very wide. When it is thin it only lets a little amount of light in. At night it gets very wide and lets lots of light in, which lets him see in the dark. Our eyes are like the green one. Our pupil cannot change very much. We can see well during the day but we find it hard to see at night. Look at your eye in the mirror and then cover your eye and uncover it. Watch your pupil. What does it do? |
